1. (2:16) Researchers conduct a study about whether TRPV4 plays a role in sunburn.

2. (4:50) They studied the TRPV4 effects on both mouse and human skin and found that TRPV4 made human sensitive to UVB. Additionally, researchers are looking for something that can inhibit TRPV4.

3. (2:17) Researchers argue that by exposing to sun’s UV, people have lower blood pressure, which reduce the chance to get heart disease and stoke.

4. (1:06) Researchers conducted several experiments to employees to examine whether brain-training games improve memory.

5. (1:55) However, the experiments show that testers improved their language skills rather than intelligence or cognition. Most of the brain-training games are not designed for language skills.

Time1-2:09
P1: introduce a thing that can deal with sun burn. block sun named TRPV4
P2: an explanation of a Phd in Duke University. If we want to know more about the pain of sunburn, we need to know more about sunburn.
P3: the most possible reason that cause sunburn is UVB. It is benefit to people's life because it can bring vitamin to people, but expose sun too much, it will lead to bad effect.
P4: a research find
Time2-4:20
P1: the first step of an experiment
P2: the next step. Test in the mouse skin and an Phd use a device to test the effect of UVB to the flow of cell.
P3: further step. UVB ...TRPV4 which cause the infill of ions which is endothelin and it will thus  intrigues TrPV4 to send calcium.
P4: apply this test to human skin to see whether the result is same
P5: detail of the experiment
P6:the result is similar
P7: the attitude of author is cautious. Now we don't know the other sub effect of TRPV4
Time3-3:12
P1: researchers think the benefit of sun exposé outweighs the bad effect. Finding said the sun exposure can reduce the blood pressure not only the risk of skin problem
P2: the comparison of heart disease and skin disease in UK. Sun will bring the Vitamin D.
P3: a research. Two group 24people. One group under the UV rays and light of lamp. One only light of lamp. 
P4: the result of research. Blood pressure was reduced in first group and no change in second. But the Vitamin D remains the same in both two group.
P5: one say so the advantage outweighs the disadvantages.
P6: plan about further search about sun exposure
Time4-1:30
P1: ask a question and introduce a study. The brain training game can help train our brains like cognitive, but how it works?
P2& P3: explain the study. Choose a group of employees to test
Time5-1:57
Nature video group say the test bring them a lot of benefits like....
And explain why - the function of language.
Them compare the paper and language game
Still have some confusion 
Author love games...
Time6-6:14
  Dinosaurs extinction because of rock
Are the extinctions all same? Cause is same but details are not
Permian extinction the biggest 
Introduce the impact of extinction, some people doubt that the rock was small why impact was so huge?
 Dr T explained the criticism
After a survey , the rock cause huge burp, green gas, then global warming, dinosaurs dead

1.        2’15
Scientists have discovered that a molecule, TRPV4, can protect against painful effects of sunburn and certain pains. Sunlight can provide people with Vitamin D and good mood, but too much sunlight may affect DNA and even cause cancer.

2.        3’45
Scientists used mice and human skin as models and found that UVB will cause calcium flow into the skin cell, but only with TRPV4 present. However, the other functions or effects of TRPV4 need to be further studied.

3.        2’16
Scientists have found that the UV rays of sunlight will trigger a compound to reduce the blood pressure. The benefits of sunlight that reduce the blood pressure far outweigh the risks of skin cancer caused by sunlight. Scientist gathered at Edinburgh to show their discovery.

4.        1’15
A woman conducted a research and found that the brain-training games may not really work. People who read nature documentaries may have better performance than people who have brain-training games.

5.        1’54
People who watched nature documentaries said they become relax, and they were proved to have better language performance in the test. The brain-training games, though still very interesting, may focus less in language and have less effect on people.ß

6.
Dr Tohver provided another explanation of the extinction of dinosaurs, rather than volcanic explosion. The comet or asteroid may crushed with the Earth and left a crater which had oil shale, then caused strong earthquake, which brought the methane out and increased the temperature of the Earth.

1'48
scientists get better understanding of the cause of sunburn pain and find a possible way to get rid of it.
2'48
scientists found that T4 inhibitor can stop the damage and itch on skin, but more tests should be done before this compound be add to suncream.
52''
it seems that brian game may not increase our brian's capacity. scientists did a experiment. first of all, they do some test about people's ability, then radomly assigned them into two groups.

2'20
UV in sunlight can reduce the risk of heart attack in people and the benefits of reducing it is more than the chance of skin cancer. researchers are now learning about whether sunlight can reduce all kinds of heart attack.
1'36
the video watched group benefit more on language skills than the brian game group, because the video focused more on language. but we cannot totally deny the benefit of brain training games.

Time1:2:30
People protect themselves from the sunburn by blocking TRPV4. But sunburn is also a signal which tells people should avoid damage.
Time2:3:43
Scientists utilize mice to get a result that the mixture of TRPV4 blockers and traditional sunblock can provide a strong protection against UVB exposure.
Time3:2:25
Researchers divided 24 volunteers into 2 sessions which showed that sun's UV rays led to health benefits much more than hurt.
Time4:1:06
A recent study argues that unlike video watch group,brain-training games group cannot improve attention.

第一次练阅读小分队，感觉题目好难，时间慢。但是相信会有收获！
2’44”
  Researchers find a molecule which can find the reason that sunburn hurt healthy people: too much ultraviolet B causes damage to DNA in skin cells, it’s a good way to conduct calcium and sodium.

4‘00”
  First researchers use normal mice and genetically engineering mice to test how their skin is hurt under UVB. Calcium is sent into skin which causes people to feel itching . A compound can stop the influxes of calcium. It still needs more test.

2’16”
  The original thought of sunburn is that a compound produced when exposing to sunshine is a reason causes high blood pressure and heart diseases. A test compares lamp which are under UV rays and only heat, showing UV ray causes blood pressure rising. Vitamin D doesn’t change. Benefits outweighs risks.

0’58”
  A doubt about whether brain game is beneficial to human brains. A test divides two groups who need to do a brain game or to watch videos.

1’42”
  Research shows that video group experienced a dramatic increase in language skills, otherwise brain game group does not have. But researchers say that we still need brain games.

4’30”

The original thought of mass extinction is the cause of volcano eruption.
An idea that a rock hit the earth causing extinction only needs a crater.
A researcher found a crater, which was recognized as a coincidence.
It still needs further discovery.
